## Detailed Description

Used to create payloads for AMPS composite messages, which are messages with a number of parts where each part is a complete message of a specific message type.

For example, a composite message type of "composite-json-binary" may be declared on the server that combines a set of JSON headers with an opaque binary payload. CompositeMessageBuilder makes it easy to assemble this payload.
